And the wind direction angle of the wind direction left and right control plate 11 and the speed of the indoor fan (23).

The indoor temperature detecting means 106 is sucked through the inlet port 3 to perform the air conditioning operation of the air conditioner that controls the indoor temperature at the temperature Ts set by the user by the driving operation means 102. The temperature Tr of the air is sensed, and the compressor driving means 108 measures the temperature Ts set by the user by the driving operation means 102 and the room temperature sensed by the room temperature sensing means 106. Drive control of the compressor 109 receives the control signal output from the control means 104 in accordance with the difference of Tr.

In addition, the wind direction control means 110 is to adjust the direction of the discharge air up and down and left and right so that the air discharged through the discharge port 7 is concentrated in accordance with the ON operation of the short-range key in a region of the room, The wind direction adjusting means 110 receives a control signal output from the control means 104 when the near key is turned on, so that the wind direction up and down control plate 9 is fixed at a predetermined downward angle (about 15 °).

Hereinafter, the effect of the discharge airflow control device of the air conditioner configured as described above and its crime prevention will be described.

4A and 4B are flowcharts showing the mode selection control operation procedure of the air conditioner according to the present invention. In FIGS. 4A and 4B, S denotes a step.

First, when power is applied to the air conditioner, the power supply means 100 converts a commercial AC voltage supplied from an AC power terminal (not shown) into a predetermined DC voltage required for driving the air conditioner, thereby driving each circuit and control means ( Output to 104).

Therefore, in step S1, the DC voltage output from the power supply means 100 is inputted from the control means 104, and the air conditioner is initialized. In step S2, the control means 104 uses the wind direction control plate 9 as an operation origin. A control signal for driving the first wind direction control motor 113 is output to the first wind direction motor driver 112 to move to the closed state.

Accordingly, the first wind direction motor driver 112 receives the control signal output from the control means 104 and drives the first wind direction control motor 113 at an angular speed of 22.5 ° / sec in a clockwise direction to control the wind direction up and down control panel. Close (9).

Subsequently, in step S3, the control means 104 transmits a control signal for driving the second wind direction control motor 115 to the second wind direction motor driver 114 to move the wind direction left and right control plate 11 to the closed state, which is the operation origin. Output

Accordingly, the second wind direction motor driver 114 receives the control signal output from the control means 104 and drives the second wind direction control motor 115 at an angular speed of 22.5 ° / sec in a clockwise direction so that the wind direction left and right control plate ( 11) Close it.

At this time, in step S4, the control means 104 determines whether a predetermined time (about 7 seconds) has elapsed by counting the driving time of the first and second wind direction control motors 113 and 115, and when the predetermined time has not elapsed. In the case of NO, it is determined that the wind direction up and down control plate 9 and the wind direction left and right control plate 11 are not completely closed, and the process returns to step S2 and the operation of step S2 or less is repeated until a predetermined time elapses.

As a result of the determination in step S4, when a predetermined time has elapsed (YES), it is determined that the wind direction up and down control plate 9 and the wind direction left and right control plate 11 are completely closed, and the flow proceeds to step S5 to determine the first and second wind directions. The motor driving units 112 and 114 stop the driving of the first and second wind direction control motors 113 and 115 under the control of the control means 104 to complete the closing operation of the wind direction up and down control plate 9 and the wind direction left and right control plate 11. This state is used as a later operating origin.

On the other hand, the initialization routine from step S2 to step S5 is also performed at the time of driving off, which means that the wind direction up and down control plate 9 and the wind direction left and right control plate 11 are positioned by an arbitrary external operation when the power is turned on or when the operation is off. If it is changed to precise position control is difficult to perform the initialization routine to completely close the wind direction up and down control panel 9 and the wind direction left and right control panel (11).

Subsequently, in step S6, the set temperature Ts, the set air volume, and the set wind direction of the room to be cooled or heated by the operation operation means 102 are input to the control means 104. In step S7, the operation / stop key (hereinafter If the operation key is not turned on (NO), the operation of step S7 or less is repeated while the air conditioner is kept in operation standby until the operation key is turned on. .

As a result of the determination at step S7, when the operation key is turned on (YES), an operation command and an operation signal are input from the operation operation means 102 to the control means 104, so that the operation of cooling or heating is performed in step S8. Further, the control means 104 outputs a control signal for driving the indoor fan motor 21 to the fan motor driving means 116.

Accordingly, the fan motor driving means 116 receives the control signal output from the control means 104 in accordance with the set air volume input by the driving operation means 102 (speed) of the indoor fan motor 21. To drive the indoor fan (23).

When the indoor fan 23 is driven according to the set air volume, the indoor air is sucked into the main body 1 through the suction port 3, at which time the temperature Tr of the indoor air sucked through the suction port 3 is room temperature. The sensing means 106 detects and outputs the control means 104.

Subsequently, in step S9, the control means 104 adjusts the wind direction angles of the wind direction up and down control plate 9 and the wind direction left and right control plate 11 according to the set wind direction inputted by the driving operation means 102. A control signal for driving the wind direction control motors 113 and 115 is output to the first and second wind direction motor drivers 112 and 114.

Accordingly, the first and second wind direction motor drivers 112 and 114 receive the control signals output from the control means 104 and drive the first and second wind direction control motors 113 and 115 to adjust the wind direction up and down control plates 9 and the wind direction. The wind direction angle of the left and right adjustment plate 11 is adjusted according to the wind direction set by the user.

Subsequently, in step S10, the indoor temperature Tr sensed by the indoor temperature detecting means 106 is compared with the temperature Ts set by the user to the operation operation means 102 to determine whether the compressor 109 is a driving condition. Determine.

The driving condition of the compressor 109 is a case in which the room temperature Tr sensed by the room temperature sensing means 106 is greater than the set temperature Ts during the cooling operation, and the room temperature ( The case where Tr) is smaller than the set temperature Ts is described. In the present invention, the cooling or heating operation will be described as an example.

As a result of the discrimination in step S10, if it is not the driving condition of the compressor 109 (NO), the process returns to the step S8 and continuously performs the operation of the step S8 or less while continuously detecting the room temperature Tr. In the case of the driving condition of the compressor 109 (YES), the control means 104 determines the operation frequency of the compressor 109 according to the difference between the room temperature Tr and the set temperature Ts. The control signal for driving the compressor 109 is output to the compressor driving means 108.

Therefore, the compressor driving means 108 drives the compressor 109 according to the operating frequency determined by the control means 104.

When the compressor 109 is driven, in step S12 the indoor fan 23 is driven while the indoor air is sucked into the main body 1 through the suction port 3, and the indoor air sucked through the suction port 3 is suspended. Foreign matter such as dust is removed while passing through the filter member 17, and the indoor air from which foreign matter such as dust is removed by the filter member 17 flows into the heat exchanger 19 while passing through the heat exchanger 19. Heat exchanged by latent heat of evaporation of the refrigerant.

The air heat-exchanged in the heat exchanger 19 is moved upward by the guide of the duct member 25 and according to the wind direction angle of the wind direction up and down control plate 9 and the wind direction left and right control plate 11 installed so as to be rotatable in the discharge port 7. Air conditioning is performed by adjusting the wind direction up and down or left and right.

In the normal operation of the air conditioner as described above, in step S13, it is determined whether the near key of the operating operation means 102 is turned on, and when the near key is not turned on (NO), the process returns to the step S12 to return to normal operation. Continue to perform steps S12 and below.

As a result of the discrimination in step S13, when the dry key is turned on (YES), the flow advances to step S14, and the control means 104 determines whether 1 second has elapsed after the near key is turned on, and when 1 second has elapsed ( In the case of YES), since the key signal corresponding to the central near-field driving mode is input from the driving operation unit 102, the control unit 104 centrally closes the central region of the room close to the main body 1 (FOCUS). Enter the mode.

As a result of the discrimination in step S14, if one second has not elapsed (NO), the flow advances to step S15 to determine whether the near-field key is on again within one second after the near-field key is turned on, and if the near-field key is not on. (NO), the process returns to the step S14, and the operation of the step S14 or less is repeated until one second elapses.

As a result of the determination in step S15, when the near key is turned on (YES), the flow advances to step S16, and the control means 104 determines whether 1 second has elapsed after the near key is turned on again, and when 1 second has elapsed ( YES), since the key signal corresponding to the left near driving mode is input from the driving operation unit 102, the control unit 104 focuses on the left region of the room close to the main body 1 (FOCUS). Enter the mode.

As a result of the discrimination in step S16, if 1 second has not elapsed (NO), the flow advances to step S17 to determine whether the near key is on again within one second after the near key is turned on, and thus the near key is not turned on. In the case of NO, the process returns to the step S16 and repeats the operation of step S16 or less until 1 second has elapsed.

As a result of the determination in step S17, when the near key is turned on (YES), the flow advances to step S18, and the control means 104 determines whether 1 second has elapsed after the near key is turned on again, and when 1 second has elapsed. In the case of YES, the key signal corresponding to the right near distance driving mode is input from the driving operation means 102, so that the control means 104 concentrates the right near distance (FOCUS) which intensively cooperates with the right area of the room close to the main body 1. Enter the mode.

As a result of the discrimination in step S18, when one second has not elapsed (NO), the flow returns to step S13 to repeat the operation of step S13 or less.

Next, the control operation of the central close mode, the left near mode and the right near mode according to the driving mode selected above will be described with reference to FIGS. 5 to 7.

First, the control operation of the central near mode will be described with reference to FIG.

FIG. 5 is a flowchart showing the operation flow of the discharge airflow control in the central short-range mode applied to the present invention. In FIG. 5, S denotes a step.

When the air conditioner enters the central near mode, the control means 104 outputs a control signal to the display means 118 for displaying the central near-field operation state of the air conditioner in step S20.

Accordingly, the display means 118 turns on the central near-field display lamp under the control of the control means 104 to display the central near-field operation state, and the control means 104 discharges the air discharged through the discharge port 7 in step S21. The control signal for driving the indoor fan motor 21 is output to the fan motor driving means 116 so that the main body 1 is centrally supplied to the room close to the main body 1.

Accordingly, the fan motor driving means 116 receives the control signal output from the control means 104 to drive the rotational speed of the indoor fan motor 21 at a turbo wind amount (about 670 RPM), and control in step S22. The means 104 outputs a control signal to the first wind direction motor driver 112 for adjusting the angle of the wind direction up and down control plate 9 so that the discharged air is concentrated at the center.

Accordingly, the first wind direction motor driver 112 receives the control signal output from the control means 104 and drives the first wind direction control motor 113 at an angular speed of 14.4 ° / SEC to adjust the wind direction up and down control plate 9. As shown in FIG. 8, after the downward movement to a predetermined angle (about 15 degrees), the driving of the first wind direction regulating motor 113 is stopped.

Subsequently, in step S23, the control means 104 outputs a control signal for adjusting the angle of the wind direction left and right control plate 11 to the second wind direction motor driver 114 so that the discharged air is concentrated at the center.

The second wind direction motor driver 114 receives the control signal output from the control means 104 and drives the second wind direction control motor 115 at an angular speed of 14.4 ° / sec to adjust the angle of the wind direction left and right control plate 11. As shown in FIG. 9 (a), some of the right angles (about, 15 degrees) and some of the left portions of the angles (about, 15 degrees) are moved so that the wind direction left and right control plate 11 faces the center. After fixing, the driving of the second wind direction control motor 115 is stopped.

Accordingly, the indoor air sucked through the suction port 3 is heat-exchanged by the latent heat of evaporation of the refrigerant flowing in the heat exchanger 19 while passing through the heat exchanger 19, and the air heat-exchanged in the heat exchanger 19 is the duct member. The discharge air flows to the center of the room according to the fixed direction of the downwardly fixed angle of the wind direction up and down control plate 9 installed at the discharge port 7 and fixed to the left and right of the right direction left and right control plate 11 with the guidance of (25). At the same time, the air volume of the air discharged in accordance with the intensive supply of the turbo air flow of the indoor fan motor 21 increases, thereby performing air conditioning in the central area.

At this time, in step S24, it is determined whether the near key is turned on again. If the near key is not turned on (NO), the process returns to step S21 and repeats the operation of step S21 or less.

As a result of the discrimination in step S24, when the near key is turned on (YES), the key signal corresponding to the central near-field driving mode stop is input from the driving operation means 102 to the control means 104, thereby providing the center of the air conditioner. In order to stop the short-range operation, the control means 104 outputs a control signal to the display means 118 to display the central near-field operation stop.

Accordingly, the display means 118 turns off the central near-field display lamp under the control of the control means 104 to display the central near-field operation stop state, and in step S26 the first and second wind direction regulating motors 113 and 115 and the indoor fan. The motor 21 returns to the cooling or heating operation mode set value before the central short-range mode, and repeats the operation of step S12 or below while continuing the normal operation in step S12.

Next, the control operation of the left near mode is described with reference to FIG.

FIG. 6 is a flowchart showing the operation procedure of the discharge airflow control in the left near mode, which is applied to the present invention. In FIG. 6, S denotes a step.

When the air conditioner enters the left near mode, the control means 104 outputs a control signal to the display means 118 for displaying the left near operation condition of the air conditioner in step S30.

Therefore, the display means 118 turns on the left near display lamp under the control of the control means 104 to display the left near operation condition. In step S31, the control means 104 discharges the air discharged through the discharge port 7. The control signal for driving the indoor fan motor 21 is output to the fan motor driving means 116 so that the main body 1 is supplied to the left side of the room close to the main body 1.

Accordingly, the fan motor driving means 116 receives the control signal output from the control means 104 to drive the rotational speed of the indoor fan motor 21 to the turbo air volume (about 670 RPM), and control in step S32 The means 104 outputs to the first wind direction motor driver 112 a control signal for adjusting the angle of the wind direction up and down control plate 9 so that the discharged air is concentrated on the left side.

Accordingly, the first wind direction motor driver 112 receives the control signal output from the control means 104 and drives the first wind direction control motor 113 at an angular speed of 14.4 ° / SEC to adjust the wind direction up and down control plate 9. As shown in FIG. 8, after the downward movement to a predetermined angle (about 15 degrees), the driving of the first wind direction regulating motor 113 is stopped.

Subsequently, in step S33, the control means 104 outputs a control signal for adjusting the angle of the wind direction left and right control plate 11 to the second wind direction motor driver 114 so that the discharged air is concentrated on the left side.

The second wind direction motor driver 114 receives the control signal output from the control means 104 and drives the second wind direction control motor 115 at an angular speed of 14.4 ° / sec to adjust the angle of the wind direction left and right control plate 11. As shown in FIG. 9 (b), the drive of the second wind direction regulating motor 115 is stopped after moving to the left predetermined angle (about 15 °).

Accordingly, the indoor air sucked through the suction port 3 is heat-exchanged by the latent heat of evaporation of the refrigerant flowing in the heat exchanger 19 while passing through the heat exchanger 19, and the air heat-exchanged in the heat exchanger 19 is ducted. The discharge airflow is concentrated on the left side of the room according to the guide of (25) and moved upward to fix the downward constant angle of the wind direction up and down control plate 9 installed in the discharge port 7 and to fix the left angle of the left and right of the wind direction left and right control plate 11. At the same time, the air volume of the air discharged in accordance with the operation of the turbo air volume of the indoor fan motor 21 increases, thereby performing air conditioning in the near-neighborhood.

At this time, in step S34, it is determined whether the near key is turned on again. If the near key is not turned on (NO), the process returns to step S31 to repeat the operation of step S31 or less.

As a result of the determination at step S34, when the short distance is turned on (YES), the key signal corresponding to the left near driving mode stop is input from the driving operation means 102 to the control means 104, so that the left near distance of the air conditioner To stop the operation, the control means 104 proceeds to step S35 and outputs a control signal to the display means 118 for displaying the left near-field operation stop.

Accordingly, the display means 118 turns off the left near display lamp under the control of the control means 104 to display a left near operation stop state, and in step S36 the first and second wind direction control motors 113 and 115 and the indoor fan. The motor 21 returns to the cooling or heating operation mode set value before the left close mode, and continues the normal operation in step S12, and repeatedly performs the operations of step S12 and below.

Next, the control operation of the right near-field mode will be described with reference to FIG.

FIG. 7 is a flowchart showing the operation procedure of the discharge airflow control in the right near-field mode applied to the present invention. In FIG. 7, S denotes a step.

When the air conditioner enters the right near field mode, the control means 104 outputs a control signal to the display means 118 for displaying the right near field operation state of the air conditioner in step S40.

Accordingly, the display means 118 turns on the right near-field display lamp under the control of the control means 104 to display the right near-field operation state, and the control means 104 discharges the air discharged through the discharge port 7 in step S41. The control signal for driving the indoor fan motor 21 is output to the fan motor driving means 116 so that the main body 1 is supplied to the right side of the room close to the main body 1.

Accordingly, the fan motor driving means 116 receives the control signal output from the control means 104 to drive the rotational speed of the indoor fan motor 21 at a turbo wind amount (about 670 RPM), and control in step S42. The means 104 outputs to the first wind direction motor driver 112 a control signal for adjusting the angle of the wind direction up and down control plate 9 so that the discharged air is concentrated on the right side.

Accordingly, the first wind direction motor driver 112 receives the control signal output from the control means 104 and drives the first wind direction control motor 113 at an angular speed of 14.4 ° / SEC to adjust the wind direction up and down control plate 9. As shown in FIG. 8, the driving of the first wind direction control motor 113 is stopped after the angle is moved to a predetermined downward angle (about 15 °).

Subsequently, in step S43, the control means 104 outputs a control signal for adjusting the angle of the wind direction left and right control plate 11 to the second wind direction motor driver 114 so that the discharged air is concentrated on the right side.

The second wind direction motor driver 114 receives the control signal output from the control means 104 and drives the second wind direction control motor 115 at an angular speed of 14.4 ° / sec to adjust the angle of the wind direction left and right control plate 11. As shown in FIG. 9 (c), the driving of the second wind direction control motor 115 is stopped after moving to the right predetermined angle (about 15 °).

Accordingly, the indoor air sucked through the suction port 3 is heat-exchanged by the latent heat of evaporation of the refrigerant flowing in the heat exchanger 19 while passing through the heat exchanger 19, and the air heat-exchanged in the heat exchanger 19 is ducted. The discharge airflow is concentrated on the right side of the room according to the fixed direction of the downwardly fixed angle of the wind direction up and down control plate 9 installed at the discharge port 7 and fixed to the right side of the wind direction left and right control plate 11 by the guidance of 25. At the same time, the air volume of the air discharged by the turbo wind volume driving of the indoor fan motor 21 increases, and air conditioning is performed in the near right.

At this time, in step S44, it is determined whether the near key is on again. If the near key is not turned on (NO), the process returns to the step S41 and repeats the operation of step S41 or less.

As a result of the discrimination in step S44, when the near key is turned on (YES), the key signal corresponding to the right near driving mode stop is input from the driving operation unit 102 to the control signal 104, so that the right side of the air conditioner In order to stop the short-range operation, the process proceeds to step S45, and the control means 104 outputs a control signal to the display means 118 for displaying the right near-field operation stop.

Accordingly, in the display means 118, the right near distance display lamp is turned off under the control of the control means 104 to display the right near distance operation stop state. In step S46, the first and second wind direction control motors 113 and 115, The indoor fan motor 21 returns to the cooling or heating operation mode setting value before the right near-field mode, and repeats the operation of step S12 or below while continuing the normal operation in step S12.

As described above, according to the discharge airflow control apparatus and method of the air conditioner according to the present invention, an excellent effect of improving the air-conditioning effect of the area by adjusting the wind direction angle and the air volume of the discharged air by a simple key operation. There is.
